Live WeightWeight (kg) WTEstimates the genetic difference between animals in live weight.Birth:BWT estimates the genetic difference between animals in live weight at birth.Weaning: WWT estimates the genetic difference between animals in live weight at 100 days of age.Post Weaning:PWT estimates the genetic difference between animals in live weight at 225 days of ageMaternal Weaning Weight (kg) MWWTMWWT ASBVs are an estimate of the ewe’s potential for milk production and ability to provide a better maternal environment. They are expressed as kilograms of live weight at 100 days of age (weaning).

Carcase TraitsFat Depth (mm) FATEstimates the genetic difference between animals in fat depth at the GR site.Post Weaning:PFAT estimates the genetic difference in GR fat depth at 45kg live weight.

Number of Lambs Weaned (%) NLWEstimates the genetic difference between animals for number of lambs weaned at each lambing opportunity.

Wool TraitsFleece Weight (%) FWEstimates the genetic difference between animals for greasy (G) or clean (C) fleece weight.Note: Both greasy and clean fleece weight are expressed in percentage terms.Yearling:YGFW or YCFW estimate the genetic difference in fleece weight at 360 days of age.

Worm ResistanceWorm Egg Count (%) WECThe WEC ASBV describes the value of an animals genes for carrying worm burdens - a combination of being genetically less likely to pick up worms and being able to cope immunologically with the worm burden. WEC ASBVs are expressed as a percentage relative to a count of 500 eggs per gram.Post Weaning:PWEC estimates the genetic difference in worm burden at 225 days of age.

Dwight hand selected the following four rams when we went to Australia in Nov. 2008. We have lambs from Rockdale 06-0346 and Rockdale 05-0182. The 2011 AI lams will be sired by Rockdale 05-0182.
